TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM ROBINSON, of Brooklyn, in the county ofKings, and State of New York, have invented certain new and usefulImprovements in Lamp-Burners; and I do hcrehydeclare that the followingis a full, clear, and exact description of the same, reference being badto the accompanying drawings, making a V portion'of this specification,in which Figures 1, 2, and 3 are centralvertical transverse sections,showing the several forms or modifications of my invention.

Figures 4, 5, and 6 are plan views of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

It frequently occurs in so-called kerosene-burners, that the oil isdrawn up the wick-tube in excess of the quantity required to supply thefiame,-in which case the excess or surplus of oil runs down the exteriorofthc aforesaid tube, and besmears the burner and the lamp to which itis attached; and furthermore, that the condensation of vapors risingfrom the lamp upon the internalsurfac'es of the burner, produces a likeresult.

The object of this invention is to obviate these objections, and to thisend it consists in the formation of a trough-like collar around thespacebetween the wick-tube and the top of the burner, whereby the properpassage of the surplus oil to the body of the lamp is more elfectuallysecured than would otherwise be the case.

The invention further consists in'a detachable external trough, wherebythe products resulting from the condensation of vapors within the burnermay be prevented from dripping over the external surface of the body ofthe lamp, and which may be applied to any ordinary form of burner.

To enable others to understand the nature and construction of myinvention, I will 'proceed to describe it with reference to thedrawings.

The base or lower portion of the burner is shown at A, and is providedwiththe vertical wick-tube B, of any suitable construction. The cap orcone ofthe burner, of any appropriate form, is indicated at G.

Formed in the top plate a of the base, A, upon each side of the -wicktube, is a narrow opening or slot, 6, which enables such oil as may flowor drip down the same to pass downward through the base to the body ofthe lamp upon which the said base may be secured, the bottom plate 0 ofthe base being furnished with suitable holes, c, in order that the saidoil may pass freely therefrom, any spreading of the surplus oil from thewicktube upon the various parts of the burner, and thence to theexterior. ofzthe lamp, being thus, in a greatm'easure, guarded against.In order to render still more certain the'passagc of the surplus oiljust mentioned through the openings 6, a trough,f, is placed around thewick-tube, and at the outer edges of the openings, in such manner thatin case any of the surplus oil'should fall upon or come in contact withthe flaring or sloping sides thereof, it will be directed downward 'tothe openings, and thus caused to pass through the same. This trough maybe made detachable, and extended above the top plate a, with the loweredges of its sides fittedinto the outermost portions of the openings Z2,as shown in figs. 1 and 4-; or it may be formed by'bending downward,into an inclined position, those parts of the aforesaidtop plateadjacent to the openings, as represented in figs. 2 and 5, care bcingtaken, in this case, to depress those parts of the plate a at the narrowedges of the wicktuhe, in such manner as to form channels a, which willguide to the openings such oil as may pass down the edges aforesaid. Itis found that the vapors rising from the oil in the lamp, when'thelatter is not-in use, condense upon the internal surfaces ofthe burner,and dripping down through the perforated sides of the said burner, passto the external surface of the said lamp; and inorder to obviate this,an annular trough, D, is so fitted upon the burner as to intercept thecondensed matter just mentioned, as it passes down, as just hereinbefore set forth, the said trough being made preferably with a flatinternal flanch, which is fitted between thecollar g of the lamp and thebase of the burner, in such manner as to be securely retained in place,at thesame time that it is'capable-of being very readily detachedtherefrom when desired, as, for instance, when his required to clean'thesame.

What I claim as my invention, and desire to secure by Letters Patent,is 1. The troughf, arranged in relation with the openings 6, at thesides of the wick-tube, substantially as and for the purpose specified.

2. The annular trough D, made detachable, and constructed with theinternal flanch, whereby it may be fitted between the burner and thelamp, substantially as and for the purposespecified.
